SAll IUEL FORTER, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO THE FORTER-MILLER ENGINEERING COMPANY, OF SAME PLACE.

GAS-PRODUCER,

SIPEOIFIGATION forming part of Letters Patent No. 670.152, dated March 19, 1901.

Application filed September 20, 1900. ;$erial No. 30,616- N model.)

To (all whom it nut/y concern.-

Be it known that I, SAMUEL FORTER, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Gas-Producers, of which the following is a specification.

In the accompanying drawings, which make part of this specification, Figure I is a vertical section on line I I of Fig. II. Fig. 11 is a top plan view, partly in section, on line II II of Fig. I. Fig. III is a detail perspective view of a grate separable from the wind-box. Figs. IV and V are detail perspective views of modified forms of grates and wind-boxes.

My invention consists of certain improvements in that class of gas-producers known as water-seal producers, which have the ash-outlet at the bottom closed by a water seal.

The objects of my invention are to simplify the construction, to distribute the air neces-' sary for combustion and gasification more uniformly over the whole bed of fuel, and to give ready access from the outside to the grates or openings through which the air passes.

Here'tofore in all producers of the waterseal type in which the fuel rests on a solid bed of ashes the air has been admitted to the fuel through openings or grates located inside of the producer, and should they get clogged up with clinkers it is almost impossible to free them from such clinkers, as they are not readily accessible from the outside. In my invention I place the grates or openings for the admission of air in the circumference of the hopper, which incloses the lower part of the fuel-bed and also contains the ashbed. I provide for awind-box all around the hoppers. This wind-box I provide with airtight doors, which when opened give access to the air-openings or grates for the purpose of cleaning them from clinkers that may accumulate. I admit the air to the wind-box through two blast-nozzles located on diametrically opposite points of the wind-box. Inside of the wind-box I provide openings or grates, through which the air is forced into the fuel. These openings or grates are distributed uniformly all over the circumference, thus insuring a perfectly uniform flow of air.

The openings for the admission of air can either be cast in the hopper or separate grates can be inserted.

I prefer to use grates of small dimensions, which can easily be removed through the doors and replaced by new ones, if the case requires. As the grates are inclined at a steep angle with the horizontal, the air entering through them is forced toward the center of the producer, thus preventing the larger portion of the air from creeping along the side walls, where it generally tends to flow unless deflected toward the center. The arrangement of the grates allows me to increase the grate area independent of the inside dimensions of the producer by simply giving the grates sufficient length. The producer can also be applied for natural draft, in which case it is only necessary to keep the doors of the wind-box open, so that the air for the grates is admitted direct from the atmosphere instead of the blast-nozzles.

In the construction of my gas-producer I provide an inverted conical-shaped hopperbase 1, suspended from and supported by columns 2 2. Preferably the hopper-base 1 is made in sections and bolted together by means of bolts 1, as shown in Fig. II. In the inverted conical portion of the hopperbase 1 is an annular opening 3. Grates 4 4 are placed in this opening and secured by flanges 4 4 against projections 5 5 of the hopperbase 1 by means of wedges 6 6. Surrounding the grates 4 4 is the wind-box 7. Located at intervals along the interior of the bottom and top of the wind-box 7 are lugs 4 4. Secured to the face of the wind-box 7 are air-tight doors 8 8.

9 9 are blast-nozzles connected to the windbox 7 and placed diametrically opposite to each other.

10 10 are poke-holes in the hopper-base 1 and located above the grates.

11 is the water seal.

Assuming the producer ready for operation,it would contain a proper amountof coal, partly ignited, resting on a body of ashes. The ashes would reach from the bottom of the water seal 11 to approximately a horizontal line through the center of the grates 4: 4. Air under pressure would be forced through nozzles 9 9 into wind-box 7 and out through the grates 4 4: into the ashes and also through the body of ignited coal contained in the producer.

The blast of air entering the producer is directed by the angular projections 49 4 toward 7 the center, thus aiding the combustion and 'lar Wind-box surrounding the exterior of the hopper-base of a gas-producer.

Having described my invention, what I claim is 1. I11 gas-producers ahopper-base, detachable grates secured within said hopper-base, a wind-box encircling said hopper-base and means for forcing air into and from said windbox.

2. A gas-producer, its hopperbase suspended on columns,detachab1e grates secured Within said hopper-base, a Wind-box encircling said grates and means for supplying air to said wind-box.

3. In a gas-producer the combination of a suspended hopper-base,openings in said base, detachable grates in said openings and supported by said base, a Wind-box surrounding said grates and means for admitting air to said wind-box.

4. In a gas-producer, the combination of a suspended hopper-base, openings in said hopper-base, detachable grates in said openings, at wind-box surrounding said grates, air-tight doors in said wind-box and means for admitting air to said wind-box.
